Heavy ions in dense heavy metals can produce massive damage like can be seen here: (Wikipedia: Collision cascade) This is very different than a typical hit in an AP system though.
UV Radiation
Radiation damage that just manage to break a single bond can often be self healing in diamondoid systems since the surrounding 3D mesh of bonds can keep the partners in place till they reform their bond (related: semi diamondoid structures).
For protection of nano-machinery against UV radiation a thin protective shell of aluminum was proposed [todo: find source - Nanosystems?]. Since metallic aluminium might have too much surface diffusion at room-temperature (?) conductive diamondoid materials might be preferable. Of interest are essentially those that give metallic reflectiveness - the same materials that give metallic reflectiveness.
Especially cross-hatched conductive nanotubes might work exceptionally well (one direction only would let through polarized light) because of their electrical conductivity that even surpasses copper. (related: management of wires and sheets) Rectennas for UV wavelengths might work too.
